have been consolidated into one new page:
August 24, 2007: The campaign to monitor blazars as described in AAVSO Alert Notice 353 continues, and observations of any and all of the ten targets are welcomed. The VERITAS telescope is currently in standby while the Arizona monsoon season progresses, but the rainy season typically ends in late August or early September. Please observe these objects now to familiarize yourself with the fields and to establish a recent baseline of behavior for future analysis.
October 30, 2007: The campaign to monitor blazars as described in Alert Notice 353 is ongoing, and the triggering thresholds for VERITAS observations have recently been updated by the PI, Dr. Markus Boettcher.
The blazar 1ES 0120+340 (1ES0120+34, AAVSO Designation 0117+33) has recently been seen just above the new triggering threshold of Rc = 17.0, and observations of this source are requested over the next several weeks. 1ES 0120+340 is located at coordinates

Notifying observers and researchers of discoveries and requests for AAVSO observing assistance
Prior to the inception of the AAVSO Alert Notice in 1974, observers were alerted to a discovery or the need for observations of an object via a post card from AAVSO HQ or, if extremely urgent, a phone call from the Director or his/her assistant.
